Table 3.

Comparison between width of keratinized tissue at baseline, 3-, and 6-month intervals using paired t-test

	Mean increase in width of keratinized tissue (mean±SD), mm	P
Baseline versus 3 months (K1)	3.2±1.61	<0.001*
Baseline versus 6 months (K2)	3±1.56	<0.001*
3 months versus 6 months (K3)	− months	0.343

*P<0.05 is considered significant, *Statistically significant value. K1 Increase in width of keratinized tissue at 3 months; K2 Increase in width of keratinized tissue at 6 months; K3 Change in width of keratinized tissue from 3 to 6 months; SD Standard deviation; mm - Millimeter; P - Probability value
